of the finger piece type in which the nose' guards are moved relatively to their support by means of spring actuated levers in order to remove them from or position them on the nose of a wearer, and an object of the invention is to provide for the mounting of the guard positioning springs in such a manner that they will be inconspicuous and 'will be protected against-blows or against handling by unskilled persons.

Another object is to provide for the removal of the guards without removing the positioning springs which, being very small,

9 which are preferably coiled into flat spiral are liable to be mislaid.

Still further objects of the invention are to'provide a pivotal mounting for the guard levers that will permit of a free and uniform swinging movement thereof but prevent axial movement or wabbling and to so arrange and connect the actuating springs that their manner of disposal will lend itself to the above ends and to the ready detachment.

and replacement of all these relatedparts.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is an enlarged top view of a pair of eyeglasses in which one of the guards is removed; Fig. 2 is an enlarged front view of a portion of the eyeglasses in proximity to one of the guards; Fig. 3 is a section on line aa Fig. 1 Fig. 4: is a perspective view of one end portion of the support for the lenses; Fig. 5 is a 'perspective View of one of the springs for positiening the guards; and Fig. 6 is an enlargaeel detail view of one of the guards.

In the present embodiment of the invention there is employed a support which con nects the lenses A. This support preferably Specification of Letters Patent.

. :aEIssUED comprises an arched bridging portion 1., and=- lens attaching devices which may be in the form of ears connected by a lens screw 3, the lens attaching devices in this instance be 111g connected with the bridging portion by portions to be hereinafter particularly de- 5 scribed, on which the nose guards are" mounted to swing.

The nose guards may be in the form oflevers made of flat stockand each having one' end formed into a fingerpiece or operating i I portion 4 and another end carrying a nose bearing portion 5 consisting of upperand' lower nose engaging pads. The levers preferably swingabout vertical axes so that they may move substantially in a horizontal plane to one side of the support, the axes of the levers being formed preferably by pivot pins 6 which are removably secured to the levers and turn iribearings 7 provided by perforating a portion of the support, head's8 being arranged on-the free or .outerends of the pivots in orderto engage' the support and hold the guards thereto.

The guardsmay be positioned by springs form and have their axes coincident with the turning axes of the guards in order that a compact structure may be obtalned. Each spring may be arranged on the same side of a lever with the support, so that a lever may be removed without removing the spring. Preferably it is arranged between the support and a lever in order that it will be protected by them. To this end each spring may surround one of the "pivots 6 and have its outer end provided with a depending projection 10 that fits in a seat or recess ll-in the support and its inner end provided with an upwardly extending project-ion 12 that fits in a seat or recess 13 in the lever of a nose guard. With this arrangement it is possible to remove the guard while its spring is held to the support and to easily thereafter remove the spring as the cooperating projecting and recessed portions on the spring and the respective members with which it is interlocked are readily moved into or out of cotiperation. 3

To further protect and conceal the springs 9 against blows and to preventthe wearer or other unskilled persons tampering with them they may be entirely inclosed. -This may be effected by providing the supportor the finger pieces with housings or caviportions of the support whichconnect the bridging portion 1 with the lens attaching devices 2 are provided with vertically opening pockets 14:, the walls of which surround the springs vertically, the pockets being closed at the tops by enlarged circular portions 15 on the levers of the nose guards. The diameter-0t the circular portion of each guard may be substantially equal to the illternal diameter of a pocket so that the circular portion may fit Within a pocket, and the upper edge of a pocket may have re cesses at 16 at diametrically opposite points to provide shoulders 17 that limit the swinging movement of the lever by engagement with opposite ends of the recesses.

In operation, a user presses the finger pieces 4 together which carries the nose bearing portions 5 away from each other, thus permitting the eyeglasses to be removed from or placed upon the nose. The springs which eflectihe movement of the nose bearing portions toward each other are completely housed .and'c'oncealed so as to be protected against blows, and to prevent unskilled persons tampering with them. The guards may be removed without removing the springs as the springs are so arranged that they may be held in their proper places on the support. This is a very desirable feature as the guards may then. be quickly attached to and detached from the support during fitting without taking the springs into consideration. The connection of the springs with the support and the guards dispenses with separate fasteners and the springs are of a 'form to give a maximum strength with a minimum size. By being secured at their inner ends to the ghards they are contracted when the guards are separated and this especially adapts them for the small housings.

It will be observed that the housings or vertically opening pockets forming the connecting portions intermediate each end of the bridge and the adjacent lens attaching portion constitute, in effect, tables on which the guard levers turn but which are open at their centers to receive the springs beneath the levers. Thus the position of each spring is clearly defined and in assembling, it is simply thrust in an axial direction into the opening which alone insures its correct position and withdrawn as easily. The flat spiral coil is held against vertical movement or distortion and restricted definitely to its proper plane of operation by the two flat, parallelbearing surfaces on either side thereof, one

constituted by the bottom wall of the hous ing and the other by the lever forming the top wall of the latter. The mode of connecting up the ends of the spring with the support and guard lever, respectively, is in accord with this arrangement, the arms or projecting lugs 12 on the inner convolutions and 10 on the outer being preferably straight and regular in form to extend out laterally at right angles parallel with the axis of the coil and take into the recesses or openings 11 and 13 in the respective parts, the former adjacent to or communicating with the opening in the lever for the reception of the pivot pin.

The pivot 6 itself is the part last applied and which maintains the others in cooperative relationship and by the bearing of the head 8 thereof on the underside of the connecting portion'while the lever, to which it is rigidly secured, has an extended bearing on the table formed by the tops of the walls of the housing on the upper side, the lever is positively held against tilting or any appreciable axial movement.

So far as the function of concealing the spring is concerned, the bottom wall of the housing is not entirely essential, the front and rear vertical walls thereof, spaced apart one behind the bther in a horizontal plane alone providing a protected intervening space for the reception of the spring between them. In fact, the front .wall by itself is almost entirely eitective to this end.
